Inventor Attorneys FRANK M. HEATH, 0F PORTLAND, OREGON.

DEFLECTOR-DAIVIPER.

Application filed November 30, 1915.

To all whom it may concern:

Be it known that I, FRANK M. HEATH, a citizen of the United States, residing at Portland, in the county of Multnomah and State of Oregon, have invented a new and useful Deflector-Damper, of which the following is a specification.

The present invention appertains to dampers for stoves and furnaces, and aims to provide a novel and improved device of that character which is operable to retain the flames within the stove or furnace until they become exhausted, instead of passing directly up the flue or chimney, thereby saving fuel, preventing soot and arresting sparks.

The present device is provided with a view to obtaining a more perfect combustion by the retention of the flames within the stove or furnace as long as possible, in order that the carbon and other volatile particles will be thoroughly consumed, to reduce the deposit of soot in the flue or chimney, and which will alsoeflect a saving of fuel and a reduction to the minimum of sparks within the chimney.

The invention embodies a bell-shaped or convexed deflector damper suspended below the outlet of the stove or furnace in the path of the products of combustion, whereby the flames are directed backwardly upon themselves or toward the coals, for the intended purposes, the damper being adjustable in order that it can be adjusted closer to or farther from the outlet to regulate the draft, and the damper also being suspended loosely in order that it can vibrate or swing as the result of a heavy draft.

It is also within the scope of the invention to provide a device of the nature indicated which is extremely simple and inexpensive in construction and manufacture, which can be readily installed upon various furnaces and stoves, and which will serve its oflice in a thoroughly practical and eflicient manner.

With the foregoing and other objects in view which will appear as the description proceeds, the invention resides in the combination and arrangement of parts and in the details of construction hereinafter described and claimed, it being understood that changes in the precise embodiment of the invention herein disclosed, can be made within the scope of what is claimed, without departing from the spirit of the invention.

Specification of Letters Patent.

Serial No. 64,296.

The invention is illustrated in the accompanying drawing, wherein Figure 1 is a vertical section of the upper portion of a stove or furnace illustrating the device applied, partly in section and partly in elevation. Fig. 2 is an enlarged plan view of the bridge member which supports the damper. Fig. 3 is a longitudinal section on the line 3-3 of Fig. 2. Fig. 4 is a cross section on the line 4ll of Fig. 2. Fig. 5 is a sectional view of a modified form of damper, the section being taken on the line 55 of Fig. 6. Fig. 6 is a plan View of the modified form.

In carrying out the invention, reference being had particularly to Figs. 1 to 4, inclusive, wherein the casing 1 of the stove or furnace is provided with an upper outlet collar 2 over which the lower end of the flue or pipe 3 is slipped, a horizontal support or bridge member 4: is seated upon the collar 2 diametrically over the outlet, and has suspended therefrom a chain or flexible element 5 carrying at its lower end the damper 6. This damper, as illustrated, is of bell-shape or is convexed, although the damper may be of various contours as may be found most beneficial. The lower end of the chain 5 has a bolt 7 which is engaged through the central portion of the damper 6, and the chain serves to suspend the damper below the outlet and for lateral and swinging movements, whereby the damper can oscillate due to the draft, thereby causing the flames to oscillate likewise in order that the heat will be expended within the casing 1. The flames in being directed toward the outlet will impinge against the deflector damper 6, and said damper will direct the flames backwardly upon or toward themselves, whereby they are retained longer in the casing than if they were allowed to pass directly into the flue or pipe 3. This provides for a maximum amount of heat and also results in the carbonaceous and other combustible particles being directed back toward the coals so that they will be consumed, instead of passing out into the chimney in the form of sparks which are so objectionable. The device thus also acts as a spark arrester, as well as reducing to a minimum or nullity the accumulation of soot within the chimney. The present device serves to hold the heat within the body of the stove or furnace, and thereby prevents the excessive heating of the flue or and to this end the bridge member 4' is so constructed as to permit the chain. 5 to be adjusted upwardly and downwardly. The

bridge member 4 embodies overlapped angle sections 8 and 9, having slots 10 extending from their inner ends and longitudinally along the corners of said sections topoints adjacent the remote ends thereof, the closed Y ends of the slots 10 being enlarged, as at 11.

The slots 10 register with one another, and have engaged therethrough a bolt 12 which has an upper head resting upon the upper section 8, and a nut 13 is threaded upon the lower end of the bolt 12 and fits snugly within the lower section 9 to prevent the rotation of the nut. The bridge member 4 is thus extensible and contractible in order that it can be adjusted for various sizes of furnace and stove outlets, the bolt 12 being readily loosened in order that the sections 8 and 9 can be slid relative to one another. One line' of the chain 5 projects through the slots 10, and the next link above the same rests upon the section 8 to support the chain, and it is evident that by sliding the chain into one enlargement 11, the chain can be readily adjusted relative to the bridge member 4 for holding the damper at the desired height.

In Figs. 5 and 6, the damper 6 is provided with upper radial fins or ribs 6*, which prevent the damper from being raised completely against the top of the casing 1 so as to completely close the outlet, since the fins or ribs 6 will space the damper slightly from the top of the casing even though the damper is raised as far as possible.

Having thus described the invention, what is claimed as new is 1. In a device of the character described, a bridge member comprising overlapped angle sections having slots extending from their inner ends, the remote ends of said slots having enlarged portions, a clamping element engaged through said slots, a chain projecting through said slots to be supported by the bridge member, the chain being movable vertically within one of said enlarged portions, and a deflector damper carried by the chain.

2. In a device of the character described, a bridge member composed of overlapped sections, means for clamping the sections at various adjustments, one section having a slot in which said means is located and having an enlarged portion at one end, a chain projecting through said slot and adapted to be shifted vertically within said enlarged portion, and a deflector damper carried by the chain.

In testimony that I claim the foregoing as my own, I have hereto affixed my signature in the presence of two witnesses.
